We’ve gotten a handful of complaints in the last month from people who couldn’t fill in the form. There have always been complaints – but we know that for thousands of people the form works fine. But the number of complaints is now too high to ignore, so I’ll be investigating what’s happening here. It could be related to the redesign of the form, and the problem may only occur on certain devices (e.g., the iPad). More later …

Update:I’ve removed a bit of unnecessary JavaScript – this might fix the problem. We’ll stay alert and see if there are any more complaints.
